Answer:
The conditional probability that I get four heads given I pulled out the weighted coin = 0.2401
Step-by-step explanation:
Probability of getting 4 heads from 4 trials for a fair coin = 0.5⁴
But given that it is the weighted coin that is pulled out,
The probability of getting 4 heads from 4 trials = 0.7⁴ = 0 2401

Step-by-step explanation:
Given that:
Price of each comb = $
15 combs were purchased in = $
To find:
Amount of discount offered on each comb.
Solution:
First of all, let us calculate the price of 15 combs at the price of $
each.
Original Price of 15 combs = Price of one comb
Number of combs = $15
Now, there is some discount provided on the purchase of 15 combs.
Discount offered on 15 combs = Original price of 15 combs - Discounted price of 15 combs =
= $45
Discount offered on each comb = Discount on 15 combs divided by 15
Discount offered on each comb =
= <em>$3</em>
